Set of paper gaskets to go between the block and gearbox on all Minis 1959-1995. Also order TRS1317 o-ring and AHU1959 front "half-moon" oil seal to do this job.

Fits MPi engine blocks only. Thin paper gasket that goes between the block lower flange and the top flange of the gearbox case. Also order TRS1317 o-ring and

Transmission synchro ring as used from 1963-on. CNC-grooved for correct shape and machined for concentricity using the original-type fixings to get the correct areas of heat treatment, plus correct degree of angles on specific areas. Aftermarket product made from Rover drawings. Sold each.

This synchro ring is CNC machined, heat treated and finally grooved for accuracy and concentricity, providing an exceptionally strong ring similar to those produced by BMC in the '60s.

First/second gear synchonizer hub assembly for all 4-synchro tranmissions. Replaces 22G2263. See also DAM7455-RING for outermost slider ring only.

Reproduction first/second gear synchonizer hub assembly for all 3-Synchro B-Type transmissions, including the classic Mini Cooper S

Third and fourth synchronising hub for all four synchromesh Mini gearboxes.

For use with Swiftune (Quiafe) drop gear sets. Idler gear shaft for use with taper-roller bearing equipped idler gear. This shaft fits pre-A+ transmission and flywheel housing.

Third gear found in a few A+ transmissions. Identified by 20 teeth and twin rings marked around the perimeter of the gear teeth.

Laygear thrust washer on 4th gear end which is one size only. The first gear end is the adjustable laygear washer end but these are obsolete on Pre A-plus layshafts. This one fits all 4-synchro gearboxes.

Small thrust washer at the end of the laygear in A+ boxes from 1979-on. Select washer thickness to achieve specified end float. This one is .124"-.126" thick.

Small thrust washer at the end of the laygear in A+ boxes from 1979-on. Select washer thickness to achieve specified end float. This one is .130"-.132" thick.

Early Mini final drives used a yoke output shaft that required u-bolts to secure the rubber or nylon u-joints. Sold each.

Used u-bolt for securing the rubber or nylon u-joints for early Mini final drive yoke output shafts.

Replacement bolt-on center for Verto flywheel; needed when the tapered inner surface is found damaged once the flywheel has been removed.

This steel outer ring saves four pounds compared to the stock cast iron Verto one. See C-AEG423 for SPI and C-AEG424 for MPI versions.

+ Special Order Item + This steel outer ring saves 4 pounds compared to the stock cast iron Verto one. Includes reluctor ring for engine management system.

This SPi-only lightened steel flywheel is machined to increase clamping pressure reducing potential clutch slip and the reluctor ring for timing is machined in the flywheel to produces maximum reliability.

A windage tray prevents oil spray from the gearbox from getting up to the reciprocating parts. It has been proven to be worth a couple of horsepower on our GT5 Racing Mini.

This is our standard racing windage tray, but with no cutout for the conventional oil pickup pipe. It is slotted only for the center web of the gear case.
